Question

Solve the following equation

1. (5/11)x=-10
a. x=-22
b. x=22
c. x=-50/11
d. x=50/11

2. (x+3)/6=12
a. x=5
b. x=15
c. x=69
d. x=72

Answer 1

1. a

2. c

Explanation:

To solve equations, use inverse operations to undo operations in the equation.

`11*(5)/(11)x=-10*11\\\\5x=-121\\(5x)/(5)=(-110)/(5)\\  x=-22`

`(x+3)/(6) =12\\\ 6*(x+3)/(6) =12*6\\(x+3)=72\\x+3-3=72-3\\x=69`
